I believe the answer is A. Windsor
A windsor chair is built with solid seat made from wood with the legs and the chair-back are round and tetoned.
The upright of the back and the back of the legs are continuous and the the seats on this chair will be carved to shallow shapes in order to provide some sense of comfort for those who sit on it
The answer is c or a because it definitely doesn’t pass through a vacuum the fastest
I would think its A. the rest of the options are for people that can stand still and focus.
The answer is definitely landslide I just took a test and got that answer correct
